* Fix table layout with no overflow
* Fix inline box breaking function
* Split replaced_min_content_width and replaced_max_content_width
* Respect text direction and don't translate rtl columns twice
* Get only first line's width of inline children to get linebox width
Changelog:
8.0.2:
Version 8.0.2 contains two small bug fixes: proper handling of pages
with no content, and better handling of files with loops following cross
reference tables.
8.0.1:
This is a very minor update from 8.0.0. It just contains two small
enhancements that missed the train: handle zlib streams with data checksum
errors, and, in the command line tool, allow specification of page numbers
counting from the end in page ranges.
Version 9.23:
Ghostscript now has a family of 'pdfimage' devices (pdfimage8, pdfimage24 and pdfimage32) which produce rendered output wrapped up as an image in a PDF. Additionally, there is a 'pclm' device which produces PCLm format output.
There is now a ColorAccuracy parameter allowing the user to decide between speed or accuracy in ICC color transforms.
JPEG Passthrough: devices which support it can now receive the 'raw' JPEG stream from the interpreter. The main use of this is the pdfwrite/ps2write family of devices that can now take JPEG streams from the input file(s) and write them unchanged to the output (thus avoiding additional quantization effects).
PDF transparency performance improvements
IMPORTANT: We are in the process of forking LittleCMS. LCMS2 is not thread safe, and cannot be made thread safe without breaking the ABI. Our fork will be thread safe, and include performance enhancements (these changes have all be been offered and rejected upstream). We will maintain compatibility between Ghostscript and LCMS2 for a time, but not in perpetuity. Our fork will be available as its own package separately from Ghostscript (and MuPDF).
We have continued the focus on code hygiene in this release cleaning up security issues, ignored return values, and compiler warnings.
The usual round of bug fixes, compatibility changes, and incremental improvements.

* Add missing ALTERNATIVES forgot from 2015.
v2.1.0 (15th Februar 2018)
- Support extra encrypted PDF variants (thanks to Gyuchang Jun)
- various bug fixes
Changes:
1.20.1
------
- libcupsfilters: Silenced warning when using CUPS < 2.x by
eliminating the use of a recently introduced CUPS library
function (Bugzilla bug #1421).
- braille: Fix some missing options on indexv4. Thanks to
Samuel Thibault for this patch (Pull request #21).
- braille: Fix disabling margins on indexv4 in graphic
mode. Thanks to Samuel Thibault for this patch (Pull request
#20).
- braille: Fix installation of brftopagedbrf. Thanks to Samuel
Thibault for this patch (Pull request #18, Issue #17).
- cups-browsed: Fixed crash when CUPS reports a print queue
without "device-uri" attribute when cups-browsed polls a
list of local CUPS queues (Issue #16).
1.20.0
------
- libcupsfilters: Let the PPD generator prefer the English
translation file from CUPS for the human-readable strings in
the PPD files.
- libcupsfilters: The PPD generator lists all page sizes with
human-readable names now, including proprietary names of the
printer.
- cups-browsed, driverless: Fixed get-printer-attributes call
on driverless printers for generating the PPD, explicitly
requesting the media-col-database attribute as otherwise
borderless page sizes do not appear.
- libcupsfilters: Fixed loading option/choice strings lists
from driverless printers for PPD file generation. Especially
proprietary media types appear correctly now.
- libcupsfilters: Completed color space support in the PPD
generator: Added DeviceGray/RGB/CMYK, default to 8 bit for
SRGB and to 16 bit for AdobeRGB, avoid duplicate listings of
the same color space.
1.19.0
------
- libcupsfilters: Let the PPD generator add the options "Print
Optimization", "Print Rendering Intent" and "Print Scaling"
if appropriate IPP attributes are found.
- libcupsfilters: Let the PPD generator read out the maximum
of info about color spaces and this way not only reliably
the correct choices are added to the ColorModel option but
also the maximum supported bit depth (8 or 16 bit) is used.
- libcupsfilters: Overtaken new features from CUPS' PPD
generator: Presets, Finishing Templates, and extraction of
media sizes from "media-col-database"
- libcupsfilters: Improvements on header of generated PPDs:
use cups-filters version number, "drvless.ppd" PCFileName,
APSupplies and cupsChargeInfoURI from CUPS.
- libcupsfilters: Let the PPD generator use the IPP string
tables in the translation files of CUPS 2.3.x or newer
(English strings only). Let all options in the PPD have
human-readable option and choice names. In case of CUPS
2.2.x or older (or if the CUPS translation are missing) we
fall back to internal tables.
- cups-browsed: Improved debug output when checking IPP
attributes of IPP printers.
- .gitignore: Ignore also core files.
- cups-browsed: Support use of PPD files generated by CUPS for
IPP Printers. Works only if the the local queue created by
cups-browsed replaces a temporary queue from CUPS.
Configurable via "UseCUPSGeneratedPPDs" directive in
cups-browsed.conf.
1.18.0
------
- braille: Add support for page-ranges option. Thanks to
Samuel Thibault for this patch (Pull request #12).
- braille: Fix supporting docx and LO file names with
spaces. Thanks to Samuel Thibault for this patch (Pull
request #11).
- .gitignore: Updated and cleaned up.
- Build system: Make sure that "make dist" always includes all
files of the repository, plus the files generated by
./autogen.sh, independent of the system configuration and
the used ./configure options.
- pdftoijs, pdftoopvp: Build pdftoijs and pdftoopvp only on
demand (via "--enable-ijs" and "--enable-opvp" on the
./configure command line). There are actually no known
printer drivers using these filters. If no one complains
about the missing filters they will get completely removed.
- Build system: Set default path for pdftops to
/usr/bin/pdftops also for cross-compiling (Bug #1417).
- cups-browsed: Set "printer-location" as an attribute and not
as an option when creating/updating a CUPS queue (Bug
#1413).
- braille: Fix handling non-printable characters in BRF
files. Thanks to Samuel Thibault for this patch.
- braille: Fix printing backslashes in BRF files. Thanks to
Samuel Thibault for this patch.
- braille: use application/vnd.cups-brf instead of
text/vnd.cups-brf. Thanks to Samuel Thibault for this patch.
- braille: Make sure liblouis emits pure BRF output. Thanks to
Samuel Thibault for this patch.
- braille: Spaces at the head of lines were not getting
embossed, because bash would eat them in the read
command. IFS allows to avoid the issue. Thanks to Samuel
Thibault for this patch.
- gstoraster: Emit proper error message if Ghostscript is
missing. Thanks to Peter De Wachter (pdewacht at gmail dot
com) for the patch (Bug #1415).
- braille: Old bash does not like quotes, like in '$(("123" +
0))'. Removed unneeded quotes. Thanks to Samuel Thibault for
this patch.
- braille: Index V5 embossers are compatible with the V4
protocol so we do not need driver changes, we just need to
advertise the support. Thanks to Samuel Thibault for this
patch.
Changelog:
2018-02-25 Jay Berkenbilt <ejb@ql.org>
* 8.0.0: release
2018-02-17 Jay Berkenbilt <ejb@ql.org>
* Fix QPDFObjectHandle::getUTF8Val() to properly handle strings
that are encoded with PDF Doc Encoding. Fixes#179.
* Add qpdf_check_pdf to the "C" API. This method just attempts to
read the entire file and produce no output, making possible to
assess whether the file has any errors that qpdf can detect.
* Major enhancements to handling of type errors within the qpdf
library. This fix is intended to eliminate those annoying cases
where qpdf would exit with a message like "operation for
dictionary object attemped on object of wrong type" without
providing any context. Now qpdf keeps enough context to be able to
issue a proper warning and to handle such conditions in a sensible
way. This should greatly increase the number of bad files that
qpdf can recover, and it should make it much easier to figure out
what's broken when a file contains errors.
* Error message fix: replace "file position" with "offset" in
error messages that report lexical or parsing errors. Sometimes
it's an offset in an object stream or a content stream rather than
a file position, so this makes the error message less confusing in
those cases. It still requires some knowledge to find the exact
position of the error, since when it's not a file offset, it's
probably an offset into a stream after uncompressing it.
* Error message fix: correct some cases in which the object that
contained a lexical error was omitted from the error message.
* Error message fix: improve file name in the error message when
there is a parser error inside an object stream.
2018-02-11 Jay Berkenbilt <ejb@ql.org>
* Add QPDFObjectHandle::filterPageContents method to provide a
different interface for applying token filters to page contents
without modifying the ultimate output.
2018-02-04 Jay Berkenbilt <ejb@ql.org>
* Changes listed on today's date are numerous and reflect
significant enhancements to qpdf's lexical layer. While many
nuances are discussed and a handful of small bugs were fixed, it
should be emphasized that none of these issues have any impact on
any output or behavior of qpdf under "normal" operation. There are
some changes that have an effect on content stream normalization
as with qdf mode or on code that interacts with PDF files
lexically using QPDFTokenizer. There are no incompatible changes
for normal operation. There are a few changes that will affect the
exact error messages issued on certain bad files, and there is a
small non-compatible enhancement regarding the behavior of
manually constructed QPDFTokenizer::Token objects. Users of the
qpdf command line tool will see no changes other than the addition
of a new command-line flag and possibly some improved error
messages.
* Significant lexer (tokenizer) enhancements. These are changes to
the QPDFTokenizer class. These changes are of concern only to
people who are operating with PDF files at the lexical layer using
qpdf. They have little or no impact on most high-level interfaces
or the command-line tool.
New token types tt_space and tt_comment to recognize whitespace
and comments. this makes it possible to tokenize a PDF file or
stream and preserve everything about it.
For backward compatibility, space and comment tokens are not
returned by the tokenizer unless QPDFTokenizer.includeIgnorable()
is called.
Better handling of null bytes. These are now included in space
tokens rather than being their own "tt_word" tokens. This should
have no impact on any correct PDF file and has no impact on
output, but it may change offsets in some error messages when
trying to parse contents of bad files. Under default operation,
qpdf does not attempt to parse content streams, so this change is
mostly invisible.
Bug fix to handling of bad tokens at ends of streams. Now, when
allowEOF() has been called, these are treated as bad tokens
(tt_bad or an exception, depending on invocation), and a
separate tt_eof token is returned. Before the bad token
contents were returned as the value of a tt_eof token. tt_eof
tokens are always empty now.
Fix a bug that would, on rare occasions, report the offset in an
error message in the wrong space because of spaces or comments
adjacent to a bad token.
Clarify in comments exactly where the input source is positioned
surrounding calls to readToken and getToken.
* Add a new token type for inline images. This token type is only
returned by QPDFTokenizer immediately following a call to
expectInlineImage(). This change includes internal refactoring of
a handful of places that all separately handled inline images, The
logic of detecting inline images in content streams is now handled
in one place in the code. Also we are more flexible about what
characters may surround the EI operator that marks the end of an
inline image.
* New method QPDFObjectHandle::parsePageContents() to improve upon
QPDFObjectHandle::parseContentStream(). The parseContentStream
method used to operate on a single content stream, but was fixed
to properly handle pages with contents split across multiple
streams in an earlier release. The new method parsePageContents()
can be called on the page object rather than the value of the
page dictionary's /Contents key. This removes a few lines of
boiler-plate code from any code that uses parseContentStream, and
it also enables creation of more helpful error messages if
problems are encountered as the error messages can include
information about which page the streams come from.
* Update content stream parsing example
(examples/pdf-parse-content.cc) to use new
QPDFObjectHandle::parsePageContents() method in favor of the older
QPDFObjectHandle::parseContentStream() method.
* Bug fix: change where the trailing newline is added to a stream
in QDF mode when content normalization is enabled (the default for
QDF mode). Before, the content normalizer ensured that the output
ended with a trailing newline, but this had the undesired side
effect of including the newline in the stream data for purposes of
length computation. QPDFWriter already appends a newline without
counting in length for better readability. Ordinarily this makes
no difference, but in the rare case of a page's contents being
split in the middle of a token, the old behavior could cause the
extra newline to be interprted as part of the token. This bug
could only be triggered in qdf mode, which is a mode intended for
manual inspection of PDF files' contents, so it is very unlikely
to have caused any actual problems for people using qpdf for
production use. Even if it did, it would be very unusual for a PDF
file to actually be adversely affected by this issue.
* Add support for coalescing a page's contents into a single
stream if they are represented as an array of streams. This can be
performed from the command line using the --coalesce-contents
option. Coalescing content streams can simplify things for
software that wants to operate on a page's content streams without
having to handle weird edge cases like content streams split in
the middle of tokens. Note that
QPDFObjectHandle::parsePageContents and
QPDFObjectHandle::parseContentStream already handled split content
streams. This is mainly to set the stage for new methods of
operating on page contents. The new method
QPDFObjectHandle::pipeContentStreams will pipe all of a page's
content streams though a single pipeline. The new method
QPDFObjectHandle.coalesceContentStreams, when called on a page
object, will do nothing if the page's contents are a single
stream, but if they are an array of streams, it will replace the
page's contents with a single stream whose contents are the
concatenation of the original streams.
* A few library routines throw exceptions if called on non-page
objects. These constraints have been relaxed somewhat to make qpdf
more tolerant of files whose page dictionaries are not properly
marked as such. Mostly exceptions about page operations being
called on non page objects will only be thrown in cases where the
operation had no chance of succeeding anyway. This change has no
impact on any default mode operations, but it could allow
applications that use page-level APIs in QPDFObjectHandle to be
more tolerant of certain types of damaged files.
* Add QPDFObjectHandle::TokenFilter class and methods to use it to
perform lexical filtering on content streams. You can call
QPDFObjectHandle::addTokenFilter on stream object, or you can call
the higher level QPDFObjectHandle::addContentTokenFilter on a page
object to cause the stream's contents to passed through a token
filter while being retrieved by QPDFWriter or any other consumer.
For details on using TokenFilter, please see comments in
QPDFObjectHandle.hh.
* Enhance the string, type QPDFTokenizer::Token constructor to
initialize a raw value in addition to a value. Tokens have a
value, which is a canonical representation, and a raw value. For
all tokens except strings and names, the raw value and the value
are the same. For strings, the value excludes the outer delimiters
and has non-printing characters normalized. For names, the value
resolves non-printing characters. In order to better facilitate
token filters that mostly preserve contents and to enable
developers to be mostly unconcerned about the nuances of token
values and raw values, creating string and name tokens now
properly handles this subtlety of values and raw values. When
constructing string tokens, take care to avoid passing in the
outer delimiters. This has always been the case, but it is now
clarified in comments in QPDFObjectHandle.hh::TokenFilter. This
has no impact on any existing code unless there's some code
somewhere that was relying on Token::getRawValue() returning an
empty string for a manually constructed token. The token class's
operator== method still only looks at type and value, not raw
value. For example, string tokens for <41> and (A) would still be
equal because both are representations of the string "A".
* Add QPDFObjectHandle::isDataModified method. This method just
returns true if addTokenFilter has been called on the stream. It
enables a caller to determine whether it is safe to optimize away
piping of stream data in cases where the input and output are
expected to be the same. QPDFWriter uses this internally to skip
the optimization of not re-compressing already compressed streams
if addTokenFilter has been called. Most developers will not have
to worry about this as it is used internally in the library in the
places that need it. If you are manually retrieving stream data
with QPDFObjectHandle::getStreamData or
QPDFObjectHandle::pipeStreamData, you don't need to worry about
this at all.
* Provide heavily annoated examples/pdf-filter-tokens.cc example
that illustrates use of some simple token filters.
* When normalizing content streams, as in qdf mode, issue warning
about bad tokens. Content streams are only normalized when this is
explicitly requested, so this has no impact on normal operation.
However, in qdf mode, if qpdf detects a bad token, it means that
either there's a bug in qpdf's lexer, that the file is damaged, or
that the page's contents are split in a weird way. In any of those
cases, qpdf could potentially damage the stream's contents by
replacing carrige returns with newlines or otherwise messing with
spaces. The mostly likely case of this would be an inline image's
compressed data being divided across two streams and having the
compressed data in the second stream contain a carriage return as
part of its binary data. If you are using qdf mode just to look at
PDF files in text editors, this usually doesn't matter. In cases
of contents split across multiple streams, coalescing streams
would eliminate the problem, so the warning mentions this. Prior
to this enhancement, the chances of qdf mode writing incorrect
data were already very low. This change should make it nearly
impossible for qdf mode to unknowingly write invalid data.
2018-02-04 Jay Berkenbilt <ejb@ql.org>
* Add QPDFWriter::setLinearizationPass1Filename method and
--linearize-pass1 command line option to allow specification of a
file into which QPDFWriter will write its intermediate
linearization pass 1 file. This is useful only for debugging qpdf.
qpdf creates linearized files by computing the output in two
passes. Ordinarily the first pass is discarded and not written
anywhere. This option allows it to be inspected.
7.1.1: release
* Bug fix: properly linearize files whose /ID has a length of
other than 16 bytes.
* Rename some test files to avoid files with three dots in their
names.
* Fix various build and compilation issues on some platforms and
compilers.
* Fix a few typos and clarify a few comments in header files.
Changelog:
2018-01-14 Jay Berkenbilt <ejb@ql.org>
* 7.1.0: release
* Allow raw encryption key to be specified in libary and command
line with the QPDF::setPasswordIsHexKey method and
--password-is-hex-key option. Allow encryption key to be displayed
with --show-encryption-key option. Thanks to Didier Stevens
<didier.stevens@gmail.com> for the idea and contribution of one
implementation of this idea. See his blog post at
https://blog.didierstevens.com/2017/12/28/cracking-encrypted-pdfs-part-3/
for a discussion of using this for cracking encrypted PDFs. I hope
that a future release of qpdf will include some additional
recovery options that may also make use of this capability.
2018-01-13 Jay Berkenbilt <ejb@ql.org>
* Fix lexical error: the PDF specification allows floating point
numbers to end with ".". Fixes#165.
* Fix link order in the build to avoid conflicts when building
from source while an older version of qpdf is installed. Fixes#158.
* Add support for TIFF predictor for LZW and Flate streams. Now
all predictor functions are supported. Fixes#171.
2017-12-25 Jay Berkenbilt <ejb@ql.org>
* Clarify documentation around options that control parsing but
not output creation. Two options: --suppress-recovery and
--ignore-xref-streams, were documented in the "Advanced
Transformation Options" section of the manual and --help output
even though they are not related to output. These are now

* Implement remaining PNG filters for decode. Prior versions could
decode only the "up" filter. Now all PNG filters (sub, up,
average, Paeth, optimal) are supported for decoding. Thanks to
Tobias Hoffmann for providing a test PDF file that has images with
all PNG filters along with different numbers of bits per sample
and samples per pixel, and thanks to Casey Rojas for providing
implementations of the remaining PNG filters.
The implementation of the remaining PNG filters changed the
interface to the private Pl_PNGFilter class, but this class's
header file is not in the installation, and there is no public
interface to the class. Within the library, the class is never
allocated on the stack; it is only ever dynamically allocated. As
such, this does not actually break binary compatibility of the
library.

Correct bug that $search_path_separator wasn't defined under msys.
Ensure that all configuration variables do have sensible default
definitions (which wasn't always the case previously).
Allow optional timeout in pvc mode after a period of inactivity.
(See documentation for -pvctimeout option.)
Compensate for problems caused by time offset between system time on
system running latexmk and file times on remote file system.
(It caused wrong behavior when a document uses biber, MiKTeX
is used, the aux_dir is on a remote file system, and the system
time on the host of the file system differs from the system time on
the system running latexmk.)
fvextra provides several extensions to fancyvrb, including
automatic line breaking and improved math mode. It also patches
some fancyvrb internals. Parts of fvextra were originally
developed as part of pythontex and minted.
This is a bundle of lua scripts and LaTeX packages for
conversion of LaTeX files to ebook formats such as epub, mobi
and epub3. tex4ht is used as conversion engine.
